Ramsay Hunt syndrome (herpes zoster oticus) occurs when a shingles infection affects the facial nerve near one of your ears. In addition to the painful shingles rash, Ramsay Hunt syndrome can cause facial paralysis and hearing loss in the affected ear.

Ramsay Hunt syndrome is caused by the same virus that causes chickenpox. After chickenpox heals, the virus lies dormant in your nerves. Years later, it may reactivate. If the virus reactivates and affects your facial nerve, the result is Ramsay Hunt syndrome.

Prompt treatment of Ramsay Hunt syndrome can reduce your risk of complications, which can include permanent facial muscle weakness and deafness.
